Building a robot dog and uploading every second of it to YouTube (Part 2) [video]

Previously posted in HN [0] about how I was going to build a robot dog and document every second of it for Youtube.

Wasn't sure if there's interest for this type of content amongst our community but that post was my most upvoted post in personal history (not a huge number but I'll take it). Was really excited and it's super encouraging to see other people upvote/follow along :)

In this part 2 I finally assembled the first leg, did some last minute CAD redesign to eliminate parts, and starting coding the servos. Ran into a ton of issues around properly initializing servos and position control, and then leg kinematics and how to model a walking motion also kicked my ass. I've left all of it in the footage, unedited, because I think someone might learn from it (?) or at least question my decisions (which would be a good exercise too).

Video is super long. My inspiration was watching George Hotz programming videos (hours long) which I really enjoy and thought there should be a hardware equivalent
